Based on five calls: wlr_render_timer_create - creates a timer which can be reused across frames on the same renderer wlr_renderer_begin_buffer_pass - now takes a timer so that backends can record when the rendering starts and finishes wlr_render_timer_get_time - should be called as late as possible so that queries can make their way back from the GPU wlr_render_timer_destroy - self-explanatory The timer is exposed as an opaque `struct wlr_render_timer` so that backends can store whatever they want in there.
